>>27835242>>27835254The byproduct of incest is blown out of proportion anyway, as long as it's first generation and not some long term "Family Project" the chances of defects are the same as a woman in her late thirties, and nowadays that's the normal age some women decide to have kids.
IIRC anything beyond first gen is doomed because of some blood condition only found in incestual children that exacerbates problems if they also have kids.
But hey, nowadays with science you can know just how fucked your kid will be and if people let an unrelated couple that knowingly will always produce a potato who's brain is just active enough for it to breath and live a couple of years, then why not let related couples at least try for something healthy?
